A laser encoding minimum cycle recognition device

Abstract

The invention relates to a laser coding minimum period identification device, comprising a receiving module, a configuration module, a coding identification module and a data module; the receiving module is used for photoelectric conversion, amplification and normalization of laser pulses; the configuration module is used for laser pulses Enrollment of pulse receiving time, and assign the laser pulse receiving time data to the code identification module; the code identification module is used to classify the data samples according to the time correlation after receiving the laser pulse receiving time data samples, and classify the classified data samples. After analyzing and finding out the code pattern characteristics of the laser code, the fuzzy decision is used to identify the minimum period of the laser code, and the laser code pulse and the laser interference pulse are back-tested; the data module is used to store and output the laser pulse receiving time data , the intermediate data and the identification result data generated during the identification process. The invention solves the problem that the current laser coding technology cannot meet the demand for laser semi-active guided weapons in modern warfare.

Description

technical field [0001] The invention relates to the field of photoelectric signal detection, in particular to a device for identifying the minimum period of laser coding. Background technique [0002] The laser semi-active guidance system consists of a laser target designator and a laser semi-active seeker on the projectile: the laser target designator emits a coded laser designation signal to the target to be attacked. The laser semi-active seeker on the projectile receives the laser signal diffusely reflected by the target, and the processor on the projectile controls the laser semi-active guided weapon to attack the target according to the laser indication signal received by the laser semi-active seeker. The accuracy of laser semi-active guided weapons can generally reach the meter level. [0003] Coding the laser indication signal is an important technical measure to identify the target to be attacked and improve the anti-jamming capability of the laser semi-active guid...
